WROUGHT-METAL BUCKLE.

Specification of Letters Patent.

Patented June 19, 1906.

To all whom, it may concern.-

Be it known that we,-GHARLEs S. HUNT- INGTON and ARTHUR S. HUNTINGTON, citizens of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have jointly invented certain new and useful Improvements in WroughtMetal Buckles, of which the following is a specification.

This invention relates"to improvements in buckles; and it has for its salient objects to rovide a strong, sightly buckle which can be more economically manufactured than could be done by previouslyknown methods. to provide a buckle of such construction that the metal may be worked cold, thus avoiding the expense and objectionable elfects due to heatin the metal, to provide a construction which ends itself to ready formation by automatic machinery, and in general to provide improvements in devices of the character re ferred to.

To the above ends the invention consists in the matters hereinafter described, and more articularly pointed out in the appended claims. j

The description will be better understood by reference to the accompanying drawings, inwhich Figure 1 is a plan view of a blank bent into shape to form a buckle and ready to be struck with the swaging-dies. Fig. 2 is an edge view of the same. Fig. 3 is a plan view of the finished buckle. Fig. 4 is a transverse sectional view taken on line 4 4 of Fig. 3. Fig. 5 is a erspective view showing one side of the buckle seen in Figs. 3 and 4 forced asunder, so as to show more clearly the form of joint by which the parts are united.

In carrying out our invention we preferably utilize drawn wire or rod metal, although the blanks may be formed of wrought metal cut into suitable strips. These blanks are so formed that when the buckle-frame has been brought to its approximate shape or outline the terminal portions of the blank overlie or overlap other portions of the frame in such manner that the ends may be united by a single stroke of asuitable swaging-die. For example, in forming the buckle-frame shown in the drawings, which buckle is of that type having a double loop and cross-bar, the blank 1, provided with obliquely out oif or beveled ends 2 2, is shaped into an approximately S form and the terminal portions extended so as to overlie and extend slightly beyondthe angles 3, formed at the junction of the crossbar portion 4 with the side-bar portions 5 and 6, respectively. Theblank is so cut that the inclined ends 2 2 both when the blank is straightt. e., before shapingand also after being brought into shape in readiness to be struck with the die, from which it resultsthat of the blank lie in planes coincident with the inner boundary of the outer frame. The blank having been thus preliminarily shaped on a suitable former, it is placed between dies and struck with suflicient force to crush the overlapping portions together, so that the side members of the buckle-frame are united to form a continuous ring-frame of substantially uniform and uninterrupted continuity. The parts are so crushed into each other that they are actually interlocked and rigidly united independently of molecular unionthat isto say, the metal is cold-swaged tothe extreme points are substantially-parallel gether in the preferred construction and accordingly the joints are not welded.

By reference to Figs. 4 and 5 it will be seen that the obliquely-cut-olf points 2 2 are swaged into the angle portions 3, and the extremities of these points lap around the inner side of the ring-frame so as to both hook over the cross-bar 4 and merge into the side-bar portions 5 and 6. Subsequent metal coating, such as nickeling or galvanizin conceals the presence of the joints when it is desired to furnish a buckle more finished in appearance. Of course the swaging to gether of the parts in the manner described cannot result in a joint the parts of which are of uniform cross-sectional area, but the slight enlargement of the frame at the points of union is almost imperceptible and not at all objectionable. The tongue, which is indicated in position in dotted lines in Fig. 3, is subsequently fastened to the cross-bar in the usual manner. Various minor changes may be made in the structure illustrated and described herein without departing from the substanceof our invention, as will be obvious to those skilled in the art.
